  KASLR should be enabled by default (x86)

Status in linux package in Ubuntu:

Bug description:
  Kernel Address Space Layout Randomization (KASLR) can make it harder
  to accomplish kernel security vulnerability exploits, especially
  during remote attacks or attacks from containers. On x86, KASLR has a
  run-time conflict with Hibernation, and currently the kernel selects
  Hibernation instead of KASLR unless the "kaslr" kernel command line
  option is given at boot time. Since the Unity desktop disabled access
  to Hibernation by default and cloud images don't use Hibernation, it
  would make sense to make KASLR enabled by default on Ubuntu. Those
  wishing to use Hibernation could just provide the "nokaslr" kernel
  command line option to flip the preference back.

  A patch to implement this already exists:
